Double piston screen changers with two cavities

Double column double working station hydraulic screen changer features, advantages, and applications:
This series screen changer designed for double channel double filter screen structure, when change screen, one screen is replaced, the other one is non-stop material flow.
The exhaust system is designed, which can fully exhaust the gas from material and waiting replaced multi-orifice, prevent changing screen process the gas was formed in product, improve product quality.
Double channel design improves filter area, which can meet higher output and higher quality production demand.
Larger filter area suits different material, different product extrusion production.
With good sealing properties, rigid sealing, long service life.
With the function of filling material, exhaust gas and pollution discharge which can insure change screen process non-stopped.
According to customer’s requirements we can specific design, process different dimensions.
Reasonable structure design, convenient operation, good effect.
The same size cylinder screen can be processed in circle, curved, Oval, cylindrical shape etc.
With safety cover design.
Applications to: chemical fiber, blown film, flat film, cast film production, pipe ,sheet, wire rod, fiber’s manufacturer, pelletizing line, recycle, etc.

Double column double working station hydraulic screen changer specifications:

Double pillar large capacity type screen changer applications: 
Compounding (master batch, filter) fibers (monofilament) pelletizing (strands and under water) recycling of most polymers. Large capacity screen changer is suitable for PP, PE, PS, PET and other plastics, especially suitable for drawing and particularly dirty material recovery granulation conditions.

Double pillar large capacity type screen changer features and advantages:
Large filtration reduces screen changing frequency, improved production efficiency
Superior sealing system completely eliminates polymer leakage.
